Where is the open circuit in the driver-side detonator circuit located?

An open circuit in the driver-side detonator circuit is generally located in front of the gear lever or beneath it. Relevant information about the four stages of the side airbag detonator is as follows: 1. Stage 1: The car crashes, reaching the detonation limit of the airbag system. The sensor takes 10ms from detecting the collision to activating the current. The detonator ignites the gas generator of the airbag, while the driver remains in an upright position. 2. Stage 2: The gas generator fully inflates the airbag within 30ms. After 40ms of the crash (at a speed of 50km/h), the driver's body begins to move forward. Since the seatbelt is diagonally fastened to the driver, it stretches as the driver moves forward, absorbing part of the impact energy generated during the crash. 3. Stage 3: 60ms after the car crash, the driver's head and upper body press against the airbag. The exhaust port behind the airbag allows the gas pressure to escape evenly under pressure. 4. Stage 4: 110ms after the car crash, the driver moves back into the seat. Most of the gas has escaped from the airbag, and the front view becomes clear again.
I've repaired quite a few airbag issues in vehicles. The most common open circuit in the driver-side inflator circuit occurs at the clock spring under the steering wheel—that rotating connector wears out the wiring during steering, causing an open circuit. Additionally, the terminals and plugs of the airbag control module are prone to oxidation and loosening. The wiring harness near the seats or floor can also get crushed or age into an open circuit. The sensor wiring interfaces aren't very reliable either, often developing poor contact after prolonged bumps. This affects airbag deployment, so don't attempt DIY fixes. Drive to a professional repair shop for diagnostic tool checks to avoid misjudgment. Safe driving is paramount—it's wise to inspect wiring conditions during regular maintenance.
I've always been concerned about car safety. The issue of airbag circuit open circuits often occurs at the wiring harness connection points on the driver's side, such as clock spring wear and open circuits behind the steering wheel, or corrosion and poor contact at the airbag module connectors. Excessive bending of the wiring near the seats can lead to breaks, and even loose terminals near the fuse box can cause open circuits. Don't underestimate this problem, as it may cause airbag failure and increase the risk of accidents. It's recommended to stop driving immediately and have it checked. Take it to a reliable repair shop for a comprehensive inspection, as they have specialized tools to locate the open circuit points. Usually, try to avoid excessive driving vibrations to protect the wiring and extend the life of the airbag system. Regularly check the warning light status to prevent potential hazards.
I've studied the airbag system, and open circuits usually occur at critical points on the driver's side. The clock spring position on the steering wheel is prone to wear and tear, leading to open circuits. Loose or aged connector plugs can also cause circuit breaks. Sensor wiring near the chassis may become loose due to vibration, and rusted fuse terminals are another common cause. This is a serious issue—airbag failure is dangerous. The safest approach is to drive to a professional shop for inspection. Safety first—don't delay.
